On the surface, Oncolytics Biotech's Q1 2024 earnings call was a standard affair. The company highlighted progress in breast and pancreatic cancer trials, eagerly anticipated overall survival data, and the continued maturation of their immunotherapy candidate, pelareorep (pela). Yet, buried within the transcript lies a potential seismic shift in strategy, one that may have flown under the radar of most analysts.

Oncolytics, with its intravenous, systemically-acting immunotherapy, has long focused on the behemoths of breast and pancreatic cancer. These indications, with their massive patient populations and urgent unmet needs, are undeniably alluring. However, they also come with immense clinical trial costs and significant competition from entrenched pharmaceutical giants.

Enter anal cancer, a rare malignancy with approximately 10,500 new cases expected in the US this year. While this patient population pales in comparison to the millions battling breast and pancreatic cancer, it presents a unique opportunity for Oncolytics - an accelerated path to market with potentially outsized returns.

The anal cancer cohort of Oncolytics' GOBLET study, evaluating pela in combination with the checkpoint inhibitor atezolizumab *without chemotherapy*, has generated remarkable preliminary results. A 37.5% objective response rate, nearly three times higher than historical controls for checkpoint inhibitors alone, is simply too compelling to ignore.

This remarkable response rate, combined with the lack of a standard of care for advanced anal cancer and the potential for accelerated approval pathways for rare diseases, suggests a strategic pivot may be underway.

Oncolytics is quietly expanding enrollment in the anal cancer cohort, aiming to enroll 18 more patients for a total of 28. Achieving seven or more responses out of these 28 patients will solidify the efficacy signal and likely propel the company towards a registrational study.

Why This Shift Matters

Speed: Completing a modest expansion cohort of 28 patients is significantly faster and cheaper than launching a full-blown registrational trial in breast or pancreatic cancer.

Regulatory Advantage: Accelerated approval pathways for rare diseases could allow Oncolytics to reach the market years earlier than in their other indications.

Proof of Concept: Success in anal cancer could serve as a powerful proof of concept for pela's ability to enhance checkpoint inhibitor efficacy in other cancers, potentially opening doors to even larger markets.

Of course, Oncolytics is not abandoning its breast and pancreatic cancer programs. However, the quiet emphasis on anal cancer suggests a shrewd prioritization that balances ambition with pragmatism.

Hypothetical Scenarios

Scenario 1: Success in Anal Cancer

Assuming rapid enrollment, data from the expanded cohort could be available in late 2025. A registrational study could be launched in 2026, potentially leading to market approval as early as 2028.

Early market entry could generate significant revenue, providing Oncolytics with the resources to fuel further development in breast and pancreatic cancer.

Success in anal cancer would make Oncolytics a more attractive acquisition target and significantly strengthen their negotiating position in potential partnerships.

Scenario 2: Mixed Results in Anal Cancer

The timeline would remain largely unchanged, but the data may not be strong enough to warrant a registrational study in anal cancer.

While revenue from anal cancer may be delayed, the company's financial position remains stable with a cash runway into 2025.

Mixed results may dampen some partner interest, but the experience gained could be valuable in designing future trials in other indications.

Scenario 3: Disappointing Results in Anal Cancer

Oncolytics would focus solely on their breast and pancreatic cancer programs, delaying potential market entry.

The company would need to raise additional capital to fund their larger trials, potentially diluting existing shareholders.

Partner interest may decrease, but positive overall survival data from BRACELET-1 could rekindle enthusiasm.

Financial Data

Market Cap: $84,412,760

Cash and Cash Equivalents (Q1 2024): $29.6 million CAD

Cash Runway: Into 2025

Earnings Call Transcript Analysis

The following chart illustrates the change in mentions of "breast cancer", "pancreatic cancer" and "anal cancer" between Oncolytics Biotech's Q4 2023 and Q1 2024 earnings calls. This provides a visual representation of the company's potential shift in focus.

It's crucial to remember that these are just hypothetical scenarios. The real story will unfold over the coming years. However, Oncolytics' quiet pivot towards anal cancer presents an intriguing narrative.

This calculated move, driven by strong early data and a favorable regulatory landscape, could prove to be a masterstroke, transforming Oncolytics from a promising development-stage company into a commercially successful biopharmaceutical powerhouse. Analysts and investors would be wise to pay close attention to this under-the-radar development.

"Fun Fact: Pela is a modified reovirus, a type of virus that is generally harmless to humans. Oncolytics leverages this inherent safety to create a targeted cancer therapy that selectively attacks tumor cells while leaving healthy cells untouched."
